Type locality. Ceylon, Colombo.
Type hosts. Mus rattus and Mus norvegicus (both domestic species are classified within Rattus now).
Principal hosts. Domestic rats of the genus Rattus (Herrin & Tipton, 1976).
Distribution. L. nuttalli is a cosmopolitan species tightly associated with its principal hosts, rats of the genus Rattus. It is found wherever domestic Rattus species occur (Herrin & Tipton, 1976). However, Mašán & Fenďa (2010) believe that L. nuttalli has not been found on the European continent until recently and mention L. dolomydis Mrciak, 1974, which closely resembles L. nuttalli, as a distinct species in the European fauna. In Asiatic Russia, the species has been recorded from the southern parts of the Far East and Eastern Siberia, including Yakutia (Nikulina, 1987, 2004; Goncharova et al., 1991).
